Prevention and therapy of cancer by dietary monoterpenes. (1/379)

Monoterpenes are nonnutritive dietary components found in the essential oils of citrus fruits and other plants. A number of these dietary monoterpenes have antitumor activity. For example, d-limonene, which comprises >90% of orange peel oil, has chemopreventive activity against rodent mammary, skin, liver, lung and forestomach cancers. Similarly, other dietary monoterpenes have chemopreventive activity against rat mammary, lung and forestomach cancers when fed during the initiation phase. In addition, perillyl alcohol has promotion phase chemopreventive activity against rat liver cancer, and geraniol has in vivo antitumor activity against murine leukemia cells. Perillyl alcohol and d-limonene also have chemotherapeutic activity against rodent mammary and pancreatic tumors. As a result, their cancer chemotherapeutic activities are under evaluation in Phase I clinical trials. Several mechanisms of action may account for the antitumor activities of monoterpenes. The blocking chemopreventive effects of limonene and other monoterpenes during the initiation phase of mammary carcinogenesis are likely due to the induction of Phase II carcinogen-metabolizing enzymes, resulting in carcinogen detoxification. The post-initiation phase, tumor suppressive chemopreventive activity of monoterpenes may be due to the induction of apoptosis and/or to inhibition of the post-translational isoprenylation of cell growth-regulating proteins. Chemotherapy of chemically induced mammary tumors with monoterpenes results in tumor redifferentiation concomitant with increased expression of the mannose-6-phosphate/insulin-like growth factor II receptor and transforming growth factor beta1. Thus, monoterpenes would appear to act through multiple mechanisms in the chemoprevention and chemotherapy of cancer.  (+info)

Biosynthesis of 3-acetyldeoxynivalenol and sambucinol. Identification of the two oxygenation steps after trichodiene. (2/379)

The first two oxygenation steps post-trichodiene in the biosyntheses of the trichothecenes 3-acetyldeoxynivalenol and sambucinol were investigated. The plausible intermediates 2-hydroxytrichodiene (2alpha- and 2beta-) and 12,13-epoxytrichodiene and the dioxygenated compounds 12,13-epoxy-9,10-trichoene-2-ol (2alpha- and 2beta-) were prepared specifically labeled with stable isotopes. They were then fed separately and/or together to Fusarium culmorum cultures, and the derived trichothecenes were isolated, purified, and analyzed. The stable isotopes enable easy localization of the labels in the products by 2H NMR, 13C NMR, and mass spectrometry. We found that 2alpha-hydroxytrichodiene is the first oxygenated step in the biosynthesis of both 3-acetyldeoxynivalenol and sambucinol. The stereoisomer 2beta-hydroxytrichodiene and 12,13-epoxytrichodiene are not biosynthetic intermediates and have not been isolated as metabolites. We also demonstrated that the dioxygenated 12, 13-epoxy-9,10-trichoene-2alpha-ol is a biosynthetic precursor to trichothecenes as had been suggested in a preliminary work. Its stereoisomer was not found in the pathway. A further confirmation of our results was the isolation of both oxygenated trichodiene derivatives 2alpha-hydroxytrichodiene and 12,13-epoxy-9, 10-trichoene-2alpha-ol as natural metabolites in F. culmorum cultures.  (+info)

Adenosylcobalamin-mediated methyl transfer by toluate cis-dihydrodiol dehydrogenase of the TOL plasmid pWW0. (3/379)

We identified and characterized a methyl transfer activity of the toluate cis-dihydrodiol (4-methyl-3,5-cyclohexadiene-cis-1, 2-diol-1-carboxylic acid) dehydrogenase of the TOL plasmid pWW0 towards toluene cis-dihydrodiol (3-methyl-4,5-cyclohexadiene-cis-1, 2-diol). When the purified enzyme from the recombinant Escherichia coli containing the xylL gene was incubated with toluene cis-dihydrodiol in the presence of NAD+, the end products differed depending on the presence of adenosylcobalamin (coenzyme B12). The enzyme yielded catechol in the presence of adenosylcobalamin, while it gave 3-methylcatechol in the absence of the cofactor. Adenosylcobalamin was transformed to methylcobalamin as a result of the enzyme reaction, which indicates that the methyl group of the substrate was transferred to adenosylcobalamin. Other derivatives of the cobalamin such as aquo (hydroxy)- and cyanocobalamin did not mediate the methyl transfer reaction. The dehydrogenation and methyl transfer reactions were assumed to occur concomitantly, and the methyl transfer reaction seemed to depend on the dehydrogenation. To our knowledge, the enzyme is the first dehydrogenase that shows a methyl transfer activity as well.  (+info)

Rhodococcus erythropolis DCL14 contains a novel degradation pathway for limonene. (4/379)

Strain DCL14, which is able to grow on limonene as a sole source of carbon and energy, was isolated from a freshwater sediment sample. This organism was identified as a strain of Rhodococcus erythropolis by chemotaxonomic and genetic studies. R. erythropolis DCL14 also assimilated the terpenes limonene-1,2-epoxide, limonene-1,2-diol, carveol, carvone, and (-)-menthol, while perillyl alcohol was not utilized as a carbon and energy source. Induction tests with cells grown on limonene revealed that the oxygen consumption rates with limonene-1,2-epoxide, limonene-1,2-diol, 1-hydroxy-2-oxolimonene, and carveol were high. Limonene-induced cells of R. erythropolis DCL14 contained the following four novel enzymatic activities involved in the limonene degradation pathway of this microorganism: a flavin adenine dinucleotide- and NADH-dependent limonene 1, 2-monooxygenase activity, a cofactor-independent limonene-1, 2-epoxide hydrolase activity, a dichlorophenolindophenol-dependent limonene-1,2-diol dehydrogenase activity, and an NADPH-dependent 1-hydroxy-2-oxolimonene 1,2-monooxygenase activity. Product accumulation studies showed that (1S,2S,4R)-limonene-1,2-diol, (1S, 4R)-1-hydroxy-2-oxolimonene, and (3R)-3-isopropenyl-6-oxoheptanoate were intermediates in the (4R)-limonene degradation pathway. The opposite enantiomers [(1R,2R,4S)-limonene-1,2-diol, (1R, 4S)-1-hydroxy-2-oxolimonene, and (3S)-3-isopropenyl-6-oxoheptanoate] were found in the (4S)-limonene degradation pathway, while accumulation of (1R,2S,4S)-limonene-1,2-diol from (4S)-limonene was also observed. These results show that R. erythropolis DCL14 metabolizes both enantiomers of limonene via a novel degradation pathway that starts with epoxidation at the 1,2 double bond forming limonene-1,2-epoxide. This epoxide is subsequently converted to limonene-1,2-diol, 1-hydroxy-2-oxolimonene, and 7-hydroxy-4-isopropenyl-7-methyl-2-oxo-oxepanone. This lactone spontaneously rearranges to form 3-isopropenyl-6-oxoheptanoate. In the presence of coenzyme A and ATP this acid is converted further, and this finding, together with the high levels of isocitrate lyase activity in extracts of limonene-grown cells, suggests that further degradation takes place via the beta-oxidation pathway.  (+info)

Olfactory discrimination ability of human subjects for ten pairs of enantiomers. (5/379)

We tested the ability of human subjects to distinguish between enantiomers, i.e. odorants which are identical except for chirality. In a forced-choice triangular test procedure 20 subjects were repeatedly presented with 10 enantiomeric odor pairs and asked to identify the bottle containing the odd stimulus. We found (i) that as a group, the subjects were only able to significantly discriminate the optical isomers of alpha-pinene, carvone and limonene, whereas they failed to distinguish between the (+)- and (-)-forms of menthol, fenchone, rose oxide, camphor, alpha-terpineol, beta-citronellol and 2-butanol; (ii) marked individual differences in discrimination performance, ranging from subjects who were able to significantly discriminate between 6 of the 10 odor pairs to subjects who failed to do so with 9 of the 10 tasks; (iii) that with none of the 10 odor pairs were the antipodes reported to differ significantly in subjective intensity when presented at equal concentrations; and (iv) that error rates were quite stable and did not differ significantly between sessions, and thus, we observed a lack of learning or training effects. Additional tests of the degree of trigeminality and threshold measurements of the optical isomers of alpha-pinene, carvone and limonene suggest that the discriminability of these three enantiomeric odor pairs is indeed due to differences in odor quality. These findings support the assumption that enantioselective molecular odor receptors may only exist for some but not all volatile enantiomers and thus that chiral recognition of odorants may not be a general phenomenon but is restricted to some substances.  (+info)

Odor response properties of rat olfactory receptor neurons. (6/379)

Molecular biology studies of olfaction have identified a multigene family of molecular receptors that are likely to be involved in odor transduction mechanisms. However, because previous functional data on peripheral coding were mainly collected from inferior vertebrates, it has been difficult to document the degree of specificity of odor interaction mechanisms. As a matter of fact, studies of the functional expression of olfactory receptors have not demonstrated the low or high specificity of olfactory receptors. In this study, the selectivity of olfactory receptor neurons was investigated in the rat at the cellular level under physiological conditions by unitary extracellular recordings. Individual olfactory receptor neurons were broadly responsive to qualitatively distinct odor compounds. We conclude that peripheral coding is based on activated arrays of olfactory receptor cells with overlapping tuning profiles.  (+info)

Biosynthesis of bitter acids in hops. A (13)C-NMR and (2)H-NMR study on the building blocks of humulone. (7/379)

The biosynthesis of humulone, an antibacterial bitter acid from hops, was studied by isotope-incorporation experiments using (13)C-labelled glucose or (2)H(2)O. (13)C enrichments, (2)H enrichments and (13)C(13)C coupling patterns identify isovaleryl-CoA, malonyl-CoA and dimethylallyl pyrophosphate as precursors for humulone. Dimethylallyl pyrophosphate, which serves as a building block for the bitter acid, is generated via the deoxyxylulose pathway of terpenoid biosynthesis. The data confirm that a symmetrical intermediate is involved in humulone formation.  (+info)

Induction by adozelesin and hydroxyurea of origin recognition complex-dependent DNA damage and DNA replication checkpoints in Saccharomyces cerevisiae. (8/379)

DNA damaging agents induce a conserved intra-S-phase checkpoint that inhibits DNA replication in eukaryotic cells. To better understand this checkpoint and its role in determining the efficacy of antitumor drugs that damage DNA, we examined the effects of adozelesin, a DNA-alkylating antitumor agent that has a profound inhibitory effect on initiation of DNA replication in mammals, on the replication of Saccharomyces cerevisiae chromosomes. Adozelesin inhibited initiation of S. cerevisiae DNA replication by inducing an intra-S-phase DNA damage checkpoint. This inhibitory effect was abrogated in orc2-1 cells containing a temperature-sensitive mutation in a component of the origin recognition complex (ORC) that also causes a defect in initiation. The orc2-1 mutation also caused a defect in a checkpoint that regulates the activation of origins in late S phase in cells treated with hydroxyurea. Defects in both initiation and checkpoint regulation in the orc2-1 strain were suppressed by deletion of a gene encoding a putative acetyltransferase, SAS2. Adozelesin also induced a cellular response that requires a function of ORC in G(1). A similar G(1)-specific response in mammals may contribute to the cytotoxic and antitumor properties of this and other DNA-damaging drugs.  (+info)

This thesis describes the development of diastereotopic group selective processes allowing the desymmetrisation of 1,4-cyclohexadiene derivatives and their application to target synthesis. Chapter 1 discusses some of the benefits that may be derived by the use of desymmetrisation, and demonstrates some of the ways in which it has recently been applied in compounds based on 1,4-cyclohexadiene. Chapter 2 describes a novel use of the Prins reaction to desymmetrise cyclohexadiene derivatives with high diastereoselectivity, and the optimisation of this resulting in an effective, practical and straightforward procedure. Chapter 3 details the investigation into desymmetrisation through diastereoselective iodocyclisation reactions, much higher stereoselectivity is observed than found previously in cyclohexadiene based substrates and an explanation is suggested by examination of structural differences.

There is substantial epidemiologic data to suggest that healthy diets, that is, those high in fruits and vegetables, decrease the risk of a variety of cancers.1 For instance, low-fat diets are associated with a decreased risk of breast and colon carcinomas.i For many dietary supplements, the precise biological mechanisms that underlie their chemopreventive activities are unknown. However, our understanding of the mechanisms underlying the anticancer activities for some dietary constituents is increasing. One example of such a constituent is limonene, which is a monoterpene that is found in a variety of citrus fruits and is a major constituent of orange peel oil.

Neutral cobalt(II) complexes of the dianionic tetrapodal pentadentate ligand B2Pz4Py, in which borate linkers supply the anionic charges, are reported. Both the six-coordinate THF adduct 1-THF and the five-coordinate THF-free complex 1 are in a high-spin S = 3/2 configuration in the ground state and have been structurally characterized by X-ray crystallography. These two Co(II) starting materials react rapidly with aryl azides of moderate steric bulk. The thermodynamic products of these reactions are low-spin, diamagnetic, Co(III) amido complexes that are either monomeric, when an external hydrogen atom source such as 1,4-cyclohexadiene is present, or dimeric products formed via C-C coupling of the azide aryl group and internal transfer of H• to the nitrogen. These products are fully characterized and are rare examples of octahedral Co amido compounds; structural determinations reveal significant pyramidalization of the amido nitrogens due to π-π repulsion wherein the amido ligand is ...

摘要: The present study involves evaluation of antioxidant potential of Crocus sativus and its main constituents, safranal (SFN) and crocin (CRO), in bronchial epithelial cells, followed antiinflammatory potential of the active constituent safranal, in a murine model of asthma. To investigate the antioxidizing potential of Crocus sativus and its main constituents in bronchial epithelial cells, the stress was induced in these cells by a combination of different cytokines that resulted in an increase in nitric oxide production (NO), induced nitric oxide synthase (iNOS) levels, peroxynitrite ion generation, and cytochrome c release. Treatment with saffron and its constituents safranal and crocin resulted in a decrease of NO, iNOS levels, peroxynitrite ion generation, and prevented cytochrome c release. However, safranal significantly reduced oxidative stress in bronchial epithelial cells via iNOS reduction besides preventing apoptosis in these cells. In the murine model of asthma study, ...

Microbial biotransformation is a relevant strategy to obtain high added value natural compounds under controlled environmentally friendly conditions. In this research work, the use of agro-residues (orange peel oil) in the biotransformation of D-limonene by a native Penicillium italicumAUMC13045 species isolated from decayed orange was evaluated. The chemical analysis of water-steam distilled orange peel oil was determined by Gass Chromatography (GC) and D-limonene was shown to be the predominant constituent, representing 82.87% of the total content. It was investigated that the highest α-terpineol yield was obtained by Malt Yeast Broth (MYB) medium at the second day after the first addition of orange peel oil. The highest α-terpineol selectivity obtained when bioconversion media inoculated with fungal conidia at the early stage of the exponential growth. The investigated samples gave higher α-terpineol yield when extracted by mixture of (1:1) diethyl ether and pentane.
Limonene is common as a dietary supplement and as a fragrance ingredient for cosmetics products.[1] As the main fragrance of citrus peels, D-limonene is used in food manufacturing and some medicines, such as a flavoring to mask the bitter taste of alkaloids, and as a fragrance in perfumery, aftershave lotions, bath products, and other personal care products.[1] D-Limonene is also used as a botanical insecticide.[1][12] D-Limonene is used in the organic herbicide Avenger.[13] It is added to cleaning products, such as hand cleansers to give a lemon or orange fragrance (see orange oil) and for its ability to dissolve oils.[1] In contrast, L-limonene has a piny, turpentine-like odor. Limonene is used as a solvent for cleaning purposes, such as the removal of oil from machine parts, as it is produced from a renewable source (citrus essential oil, as a byproduct of orange juice manufacture).[9] It is used as a paint stripper and is also useful as a fragrant alternative to turpentine.

Orange oil is an essential oil produced by cells within the rind of an orange fruit (Citrus sinensis fruit). In contrast to most essential oils, it is extracted as a by-product of orange juice production by centrifugation, producing a cold-pressed oil. It is composed of mostly (greater than 90%) d-limonene, and is often used in place of pure d-limonene. D-limonene can be extracted from the oil by distillation. The compounds inside an orange oil varies with each different oil extraction. Composition variety happens as a result of regional and seasonal changes as well as the method used for extraction. Several hundred compounds have been identified with gas chromatograph-mass spectrometry. Most of the substances in the oil belong to the terpene group with limonene being the dominant one. Long chain aliphatic hydrocarbon alcohols and aldehydes like 1-octanol and octanal are second important group of substances. The presence of sinensetin explains the orange color. Orange oil is used as a cleaner. ...

D-limonene is Probably the most common terpenes in character. Its really a important constituent in quite a few citrus oils (orange, lemon, mandarin, lime, and grapefruit). D-limonene is mentioned while in the Code of Federal Polices as usually recognized as Secure (GRAS) for the flavoring agent and can be found in frequent foods merchandise for instance fruit juices, tender drinks, baked products, ice product, and pudding. D-limonene is taken into account to have pretty minimal toxicity. It has been analyzed for carcinogenicity in mice and rats. Whilst initial outcomes confirmed d-limonene amplified the incidence of renal tubular tumors in male rats, woman rats and mice in both equally genders confirmed no proof of any tumor. Subsequent reports have identified how these tumors take place and proven that d-limonene would not pose a mutagenic, carcinogenic, or nephrotoxic threat to individuals ...

Most of them use samples from foetuses collected after legal interruption of pregnancy. In some cases, a control population is needed and foetuses aborted for non-chromosomal reasons are used. The assumption of these samples as being euploids could perhaps represent an error. In this article, we describe an easy methodology to certify the euploidy of foetal ovarian tissue using an one-week somatic culture. Using this protocol, we have obtained a primary culture in 88.2% of the studied cases, material usable for being karyotyped in 93.3% of the cases, and a cytogenetic diagnosis was performed in 100% of these cases. Finding the same karyotype ...
Article related to the NIVA course on Chemical Exposure and Cardiovascular Disease, 27th - 29th of April 2021 at Soria Moria Hotel, Oslo, Norway. The main task of the Nordic Expert Group for Criteria Documentation of Health Risks from Chemicals (NEG) is to produce criteria documents to be used by the regulatory authorities as the scientific basis for setting occupational exposure limits for chemical substances.. This criteria document reviews and evaluates the scientific literature on the association between occupational chemical exposures and cardiovascular disease (CVD), with emphasis on epidemiological data.. Occupational air pollutant exposures are often mixtures of many different chemicals, e.g. welding fumes and farming dust, which complicates exposure-effect analyses. Even individuals with their main occupational exposure restricted to one chemical (e.g. tetrachloroethylene in dry cleaning) may have a complex lifetime history of occupational exposures. CVD includes several diseases, the ...

Monoterpenes are nonnutritive dietary components found in the essential oils of citrus fruits and other plants.. A number of these dietary monoterpenes have antitumor activity.. For example, d-limonene, which comprises ,90% of orange peel oil, has chemopreventive activity against rodent mammary, skin, liver, lung and forestomach cancers. Similarly, other dietary monoterpenes have chemopreventive activity against rat mammary, lung and forestomach cancers when fed during the initiation phase.. In addition, perillyl alcohol has promotion phase chemopreventive activity against rat liver cancer, and geraniol has in vivo antitumor activity against murine leukemia cells. Perillyl alcohol and d-limonene also have chemotherapeutic activity against rodent mammary and pancreatic tumors.. As a result, their cancer chemotherapeutic activities are under evaluation in Phase I clinical trials. Several mechanisms of action may account for the antitumor activities of monoterpenes. The blocking chemopreventive ...
This article is shared with permission from our friends at Dr. Mercola.. Oranges are one of the most popular fruits in the U.S., but very few consume the peel, which is arguably the healthiest part of the whole fruit. Orange peels are rich in flavonoids, like hesperidin and polymethoxyflavones (PMFs), and other phytochemicals, which contribute many of their health benefits.. Flavonoids - antioxidant compounds found in certain fruits, vegetables, herbs, and spices - are known for their role in helping to prevent chronic diseases like heart disease and cancer.. In addition, orange peel contains higher amounts of certain nutrients than its flesh. For instance, 3.5 ounces of orange peel provides 136 milligrams (mg) of vitamin C, while the flesh contains about 71 mg.1. Orange peel also contains considerable amounts of calcium, copper, magnesium, vitamin A, folate and other B vitamins and dietary fiber.. They have an intense orange and bitter flavor, but the latter is often a clue that a food is ...
An extended model is developed to predict the free-radical thiol-ene reaction dynamics between D-limonene, as a renewable diolefin, and a monothiol compound (iso-tridecyl 3-mercaptopropionate) in bulk liquid conditions. Thermally and photo-initiated reactions of the two monomers showed favored thiol-ene coupling at the exo-isopropenyl alkene structure when reacted at 1 : 1 and 1 : 0.5 mole ratios. Experimental kinetic data obtained from the two stoichiometries were well reproduced numerically via the simulation software COPASI by introducing a multi-route mechanistic scheme with propagation-chain-transfer steps accounting for primary (mono-additions) and secondary (di-addition) modes of coupling. The differences in intrinsic double-bond reactivity enable synthesis of limonene-terminated resins (mono-versus poly-disperse) as multifunctional network precursors. Off-stoichiometry manipulations in the initial mole ratio, assisted by numerical simulations, offer a convenient approach to visualize the ...
In this study, we found that (+)- and (−)-limonene enantiomers were oxidized to respective carveol (6-hydroxylation) and perillyl alcohol (7-hydroxylation) metabolites by CYP2C9 and CYP2C19 in human liver microsomes. Although enzyme efficiencies (Vmax/Kmratio) were much higher in CYP2C19 than those of CYP2C9 in the formation of carveols and perillyl alcohols from limonene enantiomers by recombinant P450 systems, CYP2C9 was found to be more active than CYP2C19 in catalyzing limonene enantiomers by human liver microsomes with the following lines of evidence. First, sulfaphenazole, a specific CYP2C9 inhibitor, significantly suppressed the activities of oxidations of limonene enantiomers catalyzed by human liver microsomes. Second, anti-CYP2C9 IgG, which was obtained from rabbits immunized with purified human liver CYP2C9 (Shimada et al., 1986), completely inhibited limonene oxidations by liver microsomes. Third, antisera raised against CYP2C9 (purified from membranes of E. coli) inhibited very ...
The amount of bitter acids in hops is a very important parameter for beer production. Different types of hops have different quantities of alpha and beta acids, which are responsible for the bitterness of the beer. In principle the hops are divided into aromatic hops (,10% of alpha acids) and bitter hops (,10% alpha acids). A total of 12 samples were analyzed. Four were from different aromatic hops, four were from bitter hops, and the last four samples were the same variety of hops from different regions. All of the samples were applied on HPTLC MS-grade plates and developed with the AMD 2 procedure. After development the plates must be dried for 5 minutes. Then they can be directly scanned without any additional preparation steps. The advantage of TLC is that lots of samples can be applied on one plate, developed in one step and analyzed together, saving time.. ...

The aim of this study was to compare development of atherosclerotic lesions in VCD-treated and OVX±E2 mice. The rationale was based on comparing lifetime hormone profiles and temporal patterns of ovarian failure between individuals who undergo surgical (OVX) versus natural (VCD-treated) menopause. Here, in LDLR−/− mice, protection against lesion development was provided by E2 supplementation in animals given hormone before complete ovarian failure induced by VCD. In fact, E2 supplementation before or during onset of follicle depletion appeared to be more beneficial because innominate lesion area was significantly less in VCD+E2 compared with OVX+E2. This result is consistent with observations in monkeys in which E2 supplementation at the time of OVX is protective against CVD development, whereas it is detrimental if given after cardiovascular lesion progression is under way.17 Our findings suggest the timing of estrogen replacement may be critical to the subsequent influence on ...
The isomerization of limonene over the Ti-SBA-15 catalyst, which was prepared by the hydrothermal method, was studied. The main products of limonene isomerization were terpinolene, α-terpinene, γ-terpinene, and p-cymene-products with numerous applications. The amount of these products depended on reaction time, temperature, and catalyst content. These parameters changed in the following range: reaction time 30-1380 min, temperature 140-160 °C, and catalyst content 5-15 wt %. Finally, the most favorable conditions for the limonene isomerization process were established: a reaction time of 180 min, temperature of 160 °C, and amount of the catalyst 15 wt %. In order to obtain p-cymene (dehydroaromatization product), the most favorable conditions are similar but the reaction time should be 1380 min. The application of such conditions allowed us to obtain the highest amounts of the desired products in the shortest time.
